Hi ! I need to request a wake-up call for tomorrow morning .   What time do you want the call ?   I need two calls , one at 7 and another at 7 fifteen .   We can certainly do that . Expect a call from us at 7 o'colock and then again at 7 fifteen .   Actually , can I change the latter wake-up call to 7 thirty . am ?   I can certainly do that . Is there anything else ?   I can't think of anything . If I do think of something , I'll be sure to call again .   Okay . Good night , sir .
